Botany
Erect, branched shrub, growing to a height of 0.5 to 2 meters. Leaves are simple, ovate to oblong, 6-14 cm in length, round at the base, pointed at the tip. Racemes are terminal, at the axils of the leaves, 5-15 cm long, composed of numerous, thin, rounded or kidney-shaped bracts, about 2 cm long, enclosing the fasciles or dwarfed cymes of small flowers. Corolla is yellowish-green, with a tinge of purple, about 8 mm long. Pods are swollen, oblong, 1 cm long, containing 2 seeds.

Distribution
Native to the Philippines.
Abundant in settled areas, in open, dry, waste places.

Parts utilized
Leaves, flowers.

Uses
Folkloric
· Dried bracts used for stuffing pillows and cushions.
· Decoction or infusion of leaves and flowers used for tuberculosis.
· Decoction of leaves used for postpartum baths. (See:
Suob)
• In India, root paste applied externally to body swellings.
• In Nepal, Root juice (fresh roots crushed in cup of water by mortar and pestle) is taken twice daily for 7 days for diarrhea and dysentery.

• In Trinidad and Tobago, used for kidney problems.


Studies
Antibacterial:
Out of twenty-five species of ethnomedicinal plants were screened for their antibacterial activity, 13, including F strobilifera, showed positive response to at least one of the tested bacteria. F strobilifera showed positive response to two bacterial species.
Antimicrobial: A New Flavanone from Flemingia strobilifera (Linn) R. Br. and its Antimicrobial Activity: The study isolated Flemingiaflavanone which showed significant antimicrobial activity against Gram-positive bacteria ( S epidermis, S aureus, MRSA), Gram-negative bacteria (P aeruginosa, E coli) and fungi (C albicans).

Isoflavone / Antibacterial / Antioxidant: Study yielded a new isoflavone from the roots of FS and was identified as 5,7,4í-trihydroxy 8,2í,5í-tri(3-methylbut-2-enyl)isoflavone along with other known phytoconstituents. The compounds were tested in vitro for antimicrobial activity and antioxidant activity and compounds (1-3) proved to be moderately active.
Isoflavone / Antibacterial / Antioxidant: Study showed F strobilifera as an herbal medicine that can stimulate phagocytosis and play a role in immune regulation.

Availability
Wild-crafted.
